Abstract
A kind of aluminum silicate and carbon-fiber rubber sealing materials, it is made up of 50-70% aluminum silicate fiber, 5-30% fibrous skeleton, 6-18% rubber and 6-20% resol.The "dead" element of sealing material, non-corrosiveness ion do not have dust in manufacturing processed, cost is low, the intensity height, and rebound degree and rate of compression height, to human body and environmentally friendly, Application Areas is wide.
Description
The present invention relates to a kind of sealing material, especially a kind of aluminum silicate and carbon-fiber rubber sealing materials.
At present, be extensive use of the fibrous magnesium silicate sealing material in the society, and asbestos contain a large amount of dust and radioelement cobalt, they are all harmful.In recent years, people are for avoiding using the fibrous magnesium silicate sealing material, gradually adopted flexible graphite sealing material, used asbestos to do the disadvantage of sealing material, used strong acid during graphite oxidation though it has overcome, the volatilization of strong acid gas has certain infringement and pollution to human body and environment, and the sealing article intensity that graphite sealing material is made is low, and rate of compression and rebound degree are bad, and be fragile, easier fragmentation in the transportation has the corrosive (C that has that is difficult to overcome in this sealing material
1-) and (S
2-) ion, so Application Areas is also narrower.
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and provide a kind of harmless, parts are not had burn into acid and alkali-resistance, high temperature resistant, Application Areas is wide, cost is low aluminum silicate and carbon-fiber rubber sealing materials.
The objective of the invention is to realize: aluminum silicate and carbon-fiber rubber sealing materials by following measure, it is characterized in that the fibrous skeleton of its aluminum silicate fiber by 50-60%, 5-30%, the rubber of 6-18% and the phenolic resin of 6-20% form, also can be to sulphur, stearic acid, zinc oxide and promotor, the anti-aging agent of the ground barium sulfate that wherein adds 4-20%, silica powder, talcum powder, Feldspar Powder one or more and 1-3% wherein.Raw material is prepared in proportion, put into stirrer and stir, roller method making sheet in 10 ℃ of-120 ℃ of temperature ranges just becomes the desired seal material.The sealing material plate that makes is struck out needed pad, with pad and the synthetic desired seal part of tinsel, again sealing member is placed 10-20Kg/cm then
2Sulfuration promptly becomes the sealing material goods under pressure and 120 ℃ of-170 ℃ of temperature.Also confected materials can be put into stirrer and stirred, in 10 ℃ of-120 ℃ of temperature ranges,, can make the packing_seal material, press shape after in 10 ℃ of-120 ℃ of scopes, soaking fat then, also can get the sealing material goods through being spun into line.
Purpose of the present invention can also realize by following measure: the fibrous skeleton in the aluminum silicate and carbon-fiber rubber sealing materials refers to carbon fiber and flaxen fiber.Rubber refers to natural rubber, paracril, viton, phenylene silicone rubber.
The present invention has following advantage compared with prior art: 1, owing to the "dead" element of aluminum silicate and carbon-fiber rubber sealing materials, do not have dust in manufacturing processed; the fibrous magnesium silicate sealing material that can replace that dust is arranged and have the radioelement cobalt in manufacturing processed helps human beings'health and environment protection.2, owing to the non-corrosive ion of aluminum silicate and carbon-fiber rubber sealing materials, it is narrow to overcome the graphite sealing material Application Areas, breakable shortcoming.3, aluminum silicate and carbon-fiber rubber sealing materials have also that cost is low, intensity is high, rebound degree and the high advantage of rate of compression.
Accompanying drawing is aluminum silicate and carbon-fiber rubber sealing materials and goods technical process thereof.
